I'm thinking on purchasing a couple of filters mainly CPL, Grad ND and ND4/8 filters for landscape shots during my upcoming 3 months trip to New Zealand. I was looking at the below 2 videos by Phtographer Adam Barker and had a couple of questions. Hope you guys can help me out here.
How to Hand Hold Grad ND Filters - AdamBarkerPhotograph
Outdoor Photography: Shooting with a reverse grad filter & polarizer
1) What are the benefits of using Filter Holders (eg. more stable)?
2) Since attaching the Filter Ring & Filter Holder would take some time, won't the above technique save time (setting up the filter holder) as well as money (buying the filter ring & holder)? Probably answer from (1) might answer this question too.
Really appreciate if you could offer your kind advice.
